i was using gimli at the black gate on legendary level going after one of the captains and i ended up "underground" looking up at orcs walking just above me. i was even able to throw a bomb above ground but couldn't figure out how to get back. i ended up running across a long orange field and off a cliff, where i fell for a long time before dying. haven't been able to re-create this but it happened when i was holding R2 a lot aiming gimli's bomb, and after one went off i was trapped under one of the large mounds of earth looking up at the orcs. anyone had this happen? probably just a glitch but it was surreal.
